  • Bitcoin

The  Mk4 is a state-of-the-art, ultra-secure hardware wallet designed to keep your cryptocurrency safe. Featuring multiple advanced ways to connect, robust security measures, and a sleek, rugged design, the COLDCARD ensures that your crypto assets are protected from both online and physical threats. With its air-gapped operation, it never needs to touch a computer, and its advanced physical and digital security mechanisms make it a top choice for the security-conscious Bitcoin user.

Key Features & Specifications:

  • Multiple Connection Options:

    • USB-C Connector: Industry-standard for transmitting both data and power through a single cable.
    • AirGap SneakerNET: Maximum security for transferring data between devices without direct connection.
    • NFC Tap: Secure, short-range wireless transmission for easy data transfer to your phone.
    • Virtual Disk Mode: COLDCARD emulates a USB disk drive, allowing simple drag-and-drop file transfers.

  • Security Features:

    • Genuine vs. Caution Lights: Resists physical attacks (e.g., "Evil Maids") with a secure firmware signature verified during boot-up.
    • Anti-Phishing Words: Two unique words displayed during PIN entry protect against trojan-horse attacks.
    • Physical Security: Clear case for visible tampering detection, enhanced PCB design for anti-probing, and no factory reset to ensure your secrets remain safe.
    • Rugged Protective Cover: Slide-on cover protects the screen and prevents hardware implant tampering.
    • Ultra-Secure Chips: Utilizes Microchip’s ATECC608 and Maxim’s DS28C36B secure elements for critical seed phrase storage.

  • Air Gap Operation:
    COLDCARD works entirely offline, powered via USB power pack or AC adapter, including all setup, PIN selection, seed word generation, and transaction signing—ensuring full air-gap security.

  • Unique Seed Generation & Dice Roll:
    If you don’t trust the built-in random number generator, you can generate a BIP39 seed phrase using a dice roll method. Up to 99 rolls are recommended, with full verification of the process.

  • Display & Input:

    • Bright OLED Screen (3128x64 pixels): Clear, high-resolution display for ease of use.
    • Numeric Keypad: Simple, secure PIN entry.
    • Sliding Cover: Protects the screen from damage and tampering.

  • NFC Compatibility:
    The COLDCARD Mk4 supports NFC-V, allowing tap-to-transmit all data types securely.

  • Durability & Design:

    • Sleek & Rugged Build: Classic calculator-inspired sliding cover that adds protection while offering a compact, durable design.
    • No Factory Reset: Once your PIN is set, there is no way to reset it. Losing access to your PIN means losing access to your crypto, reinforcing the security of your device.
